MACHINE FOR PRINTING OIL-CLOTH AND OTHER FABRICS.

SPECIFICATION forming part of Letters Patent No. 367,351, dated July 26, 1 887.

.Application filed January 2, 1886. Serial No. E1422. (No model.)

To all whom, it may concern.-

ing Oil-Cloth and other Fabrics and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use'the same.

This invention relates to certain new and useful improvements in machines for imprinting the patterns or designs upon oil-cloths and other fabrics; and it consists, substantially, in the same as constructed and in the particular arrangement and combinations of parts, to be hereinafter distinctly described, and pointed out in the claims.

The objects of the invention are to dispense with the vast amount of gearing heretofore employed in machines-of a like character and to reduce the number of parts of the machine proper to a minimum, at the same time rendering or providing a machine that is positive in operation and most thoroughly'effective in accomplishing the work to be done, further objects being cheapn'ess of cost and ease with which the same may be manufactured and put together.

In order that others skilled in the art may understand my invention, I will refer to the accompanying sheets of drawings, in which- Figure 1 represents a longitudinal side elevation of an apparatus embodying the principles of my invention. Fig. 2 is a longitudinal vertical sectional elevation of the same. Fig. 3 is a horizontal sectional plan, and Figs. 4, 5, and 6 are views in detail,of several of the parts contributing toward my improvements. Fig. 7 represents a vertical sectional view of a machine embodying my invention, the same being taken on the line 00 w of Fig. 1, and is intended to represent more clearly the construction and relative arrangement of parts.

Fig. 8 is a detail perspective view to represent more clearly the manner of guidance between the strips a 'a of the vertical sliding bars i and the manner of operation of the brackets T as the rolls i descend to the bottom of the notches in the slides C. I

Reference being had to the several parts by the letters marked thereon,A A represent the two'sides of the framing which constitutes the supporting-structure of the operating mechanism, from which extend vertical strips a (1, across which are supported longitudinal strips '12. Between the two sides of the frame-work,

at near each end, are rolls or drums 0 (Z, around which travels an endless metal band or rib bon, e.

0 represents a reciprocating slide having, at intervals of its length, the V-shaped depressions or notches g g, which correspond to vertically-reciprocating bars or rods 2', having in their lower end a pulley orwheel, 1" i. It will be understood that while reference is made to a part on one side of the machine, there is a corresponding part on the other-as, for instance, there are two slides, 0, one on each side of the machine, the same being guided lengthwise between upper grooved friction-pulleys, X, and lower ones, 1 2 3 4t 5. The said slides are united by a cross-strip, h, from which extends, centrallyof the machine, a portion, 70, which forms a part of the slide, the same being supported at its outer end similarly as are the ends of-slide O. The said portion is formed for its lengthwith a sinuous slot, Z, as shown, and at the opposite end of the machine the two slides are formed correspondingly with similar slots, on.

D represents a crank-shaft having its bearing at one end of the machine, and which is connected to the slides 0 through the medium of the connecting-rod n, secured at one end to a rod or bar, 0, which unites the two slides, as shown.

E represents a rod, whose upper end is pivotally connected to a reciprocating carrier, E, which operates theinking-rollers and troughs F, and whose lower end is pivoted to a link, F, carrying a roller which worksin the slot m.

Centrally of the machine, at the opposite end, a pinion, H, is carried by the shaft G. This pinion meshes with a toothed rack, I, extending vertically from the extension 70 of the slides, and keyed to the same shaft, directly adjacent to the pinion, is a toothed wheel, 10, which is engaged by a dog, q, pivoted to the outer face of the pinion. fuller illustration.) The vertically-sliding (See Fig. 5 for a otherwise secured.

bars i 011 each side of the machine serve be tween them to carry the blocks 8 s, tothe under surfaces of which are attached the printing-dies.

For the purpose ofa more positive and uniform passage of the belts around their pulleys, I prefer to form such belts and pulleys approximately in the form of a sprocket-wheel and belt--that is, at regular intervals of the periphery of the pulleys 1 form indentations or depressions i, into which are received teats 0r projections corrcs pondingl y arranged on the under side of the belts, (see Fig. 4;) and in order that the cloth or fabric will be maintained perfectly in place, and thus avoid blurring in the printing operation, I provide blocks a u on the upper surface of the bands, having at their outer ends upwardly-proiccting pins or guides 12, between which the fabric or cloth is maintained perfectly in place, and thus there can be no inconsistency either in the positive working of the belts or of the cloth with respect thereto, it being intended that the pins '1) shall penetrate the fabric from the underside at or near its edges. (See Fig. 6.)

The operation of myinvention is as follows: The machine being started by any suitable power and the crank-shaft D caused to revolve, the slides G will be caused to move forward to about the extent of length of the slots at therein. This movement will cause the sliding bars'i to move upwardly over the top edge of the slides, and consequently the printing-dies s will be raised therewith. At the same time the rod E will be caused to move forward at its upper end by virtue of the slot m in the slides G, and the rolls F will be carried under the printing-dies to supply them with the ink or mixture contained in the trough. In this manner there will be an alternate]y-reeiprocating movement of both the slides U and the carrier E, and also of the sliding rods Simultaneously with this ac tion the rack I will be raised or elevated by virtue of its bearing in the slotZ of extension 7., and in being elevated it will revolve the pinion on the shaft G, and the dog, engaging the toothed wheel 1), will revolve said wheel and, accordingly, the shaft to which it is keyed or On the return movement of the slides the rack descends and the dog (1 jumps or slips the teeth in wheel p,and consequently no action of the shaft is given on this reverse or return movement. It will thus be seen that a positive movement of the belt is obtained, and that by virtue of the sprocket connection between the belts and pulleys no slips can possibly occur. The cloth or fabric traverses the machine centrally thereof between the two belts, as will be understood, and it will be apparent that a perfect unison of operation will be had. The printingdies are alternately elevated and inked and caused to be brought down upon the cloth at such intervals and with sufficient force as to perfectly imprint the design or pattern thereon, and it will be obvious that a thoroughly perfect result will be accomplished in the working of the parts in the manner explained.

As a means of causing the die-blocks to be brought down firmly upon the fabric, I provide stationary brackets T on the slides G,ad-

jacent to the rollers in the bars 2' when in their normal position. These brackets serve to receive the rollers as the dies are broughtdown, and cause them to bind slightly for the purpose mentioned.

The slide 7.r,which is located centrally of the main slides,is for the purpose of operating the racks through the medium of which the belt-carrying pulleys are operated; and it will be apparent that as the slides O are operated back and forth the said slide 7; will act to operate the racks in the manner described, and the belt thereby actnated,as explained.

By referring to Fig. 8 it will be seen that the vertically-sliding bars 1', which carry the dies,are guided between the strips a (1, thereby insuring precision of action in a true vertical line; and it will also be observed,by reference to said figure, that as the slides G are reciprocatcd the rolls i will be caused to rideupon the top edge ofthe said slides, and that as the notches are reached they will descend to the bottom thereof, thereby causing the dies to be brought down on the fabric. The brackets T are secured to the outer side of the slides 0 adjacent to the notches, the said brackets being of the form shown and of such height as that when the rolls descend to the bottom of the notches these brackets will slightly bind upon their top edges and thus prevent blurring action of the dies. It is evident that the movement of the slides C is such that these brackets T will be carried away from the edge of the rolls in time to permit the upward movement of the rods 2 and that no interference is had with a perfect operation of the parts in the manner explained.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination of reciprocating slides, the endless belt, the vertically-sliding bars, and means whereby each is operated, substantiall y as described.

2. The combination of the reciprocating slides, the endless belts, the vertically-sliding bars carrying the blocks and dies, the reciprocating trough-carriers, and means whereby each is operated, substantially in the manner set forth and described.

3.

4. The combination of the frame having the anti-friction guide-pulleys, the reciprocating ICC IIO

slides moving therein and formed with slots in, the rods E, having links F moving in such slots, the reciprocating carriers, the troughs and their rolls, the sliding bars i, the blocks and dies, and brackets T, the endless bands, and means whereby they are operated, substantially as described.
